PySide2 QSlider expanding drawable area and tick label customization

[Vesnog]

If your custom drawing code needs more space than the Slider would normally allocate, you can try overriding sizeHint() and minimumSizeHint() to ask the layout for more space.

Alternatively using a custom style of proxy style and requesting a larger area in sizeFormContents()

Thanks for your answer, I solved it by using style sheets and defining custom groove lengths as can be seen in my post on stackoverflow. I will try your solution when I have the time.
